Founded in 2000 with just two machines in a modest workshop, Leader Proto Co., Ltd has grown through perseverance and precision. 

In 2017, we officially established the brand Leader Proto to meet growing global demand for fast, reliable, and high-quality custom parts. 

Today, we stand as a trusted one-stop manufacturing solution provider, delivering exceptional service and stable quality parts to clients in over 50 countries.

Our comprehensive capabilities cover CNC machining, sheet metal, additive manufacturing, surface finishing, and assembly, all in one.

What makes us different is our end-to-end, solution-driven approach. From design feasibility analysis, material selection, DFM feedback, to final production and delivery, our engineers and project managers collaborate closely with clients to provide a smooth and efficient experience. 

This reduces turnaround time, avoids rework, and ensures the parts not only meet specs—but exceed expectations.

Backed by our ISO9001-certified quality system and a team of highly skilled technicians, we ensure every part is delivered with precision, consistency, and care. We prioritize transparency, communication, and proactive problem-solving, promising feedback or solutions within 8 working hours.
